下棋要注意棋形,初学者不注意棋形,容易下出似是而非之着。图一(正着) 黑1占角,白2挂至6是正着,白6若于A飞,也是正着,白方棋形完整。图二(正着) 白4拆,也是正着,白4若于A位也是正着。这样先拆边,留有B位点角手段。图三(错着) 白4先飞,再在6高拆,是错着,原因是4与6的结构不好。这个形放在那里,白已无好点可补,但黑方在适当时机却可侵入,见下图。图四(理由) 黑1伺机侵入,至黑7飞出,黑棋在边上活出一块,此时即可看出白和黑的交换,白棋亏了。如果事先没有这两手交换,白棋就不怕黑1侵入。这是图二与图三的不同之处。图五(错着) 白4不先在A飞,而低拆二,也是错着。接着,白棋没有好的后续手段,黑棋却有。
Play chess should pay attention to chess, beginners do not pay attention to chess, easy to come out right and wrong. Figure 1 (moving) black 1 corner, white 2 linked to 6 is positive, white 6 if A fly, but also forward, White square chess complete. Figure 2 (moving) White 4 dismantled, but also forward, white 4 if the A is also positive. This first demolition edge, leaving B point angle means. Figure three (wrong) white 4 first fly, then 6 high demolition, is wrong, because the structure of 4 and 6 is not good. The shape is put there, white has no good points to make up, but Black can invade the appropriate time, see below. Figure 4 (reason) Black 1 opportunistic invasion, to fly out of black 7, Black live on the edge of a block, then you can see the exchange of white and black, white loss. If there is no prior exchanges between these two hands, White is not afraid of Black 1 intrusion. This is the difference between figure two and figure three. Figure 5 (wrong) White 4 not first fly in A, while the low split two, is also wrong. Then, White does not have a good follow-up, Black has it.
